"doesn't work with ioctl" is what you meant, I believe, since if it were working you wouldn't need our help...
I asked before and ask again, is this actually RS-232? If it plugs into USB, the answer is probably no. And if the answer is no, the usual serial niceties like flow control probably aren't going to work how you want, making a lot of fancy termios things pointless.

UMCT(4) BSD Kernel Interfaces Manual UMCT(4)NAME
umct -- Magic Control Technology USB-RS232 converter driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device umct
device ucom
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
umct_load="YES"
DESCRIPTION
The umct driver provides support for USB to RS-232 converters based on the Magic Control Technology USB-232 design. These devices support
most of the standard RS-232 features including baud rates ranging from 300 to 115200 bits per second. However, neither hardware nor software
flow control seems to be supported.
Access to devices under this driver is via the ucom(4) framework and device nodes.
HARDWARE
The umct driver supports the following adapters:
o Belkin F5U109
o Belkin F5U409
o D-Link DU-H3SP USB BAY Hub
o Magic Control Technology USB-232
o Sitecom USB-232
SEE ALSO tty(4), ucom(4), usb(4)HISTORY
The umct driver appeared in FreeBSD 5.2. It is loosely based on the ubsa(4) driver by Alexander Kabaev <kan@FreeBSD.org> with documentation
from Wolfgang Grandeggar <wolfgang@cec.ch>.
AUTHORS
The umct driver was written by Scott Long <scottl@FreeBSD.org>.
